+/**
+ * Converts between objects with getter and setter methods and arrays.
+ *
+ * The normalization process looks at all public methods and calls the ones
+ * which have a name starting with get and take no parameters. The result is a
+ * map from property names (method name stripped of the get prefix and converted
+ * to lower case) to property values. Property values are normalized through the
+ * serializer.
+ *
+ * The denormalization first looks at the constructor of the given class to see
+ * if any of the parameters have the same name as one of the properties. The
+ * constructor is then called with all parameters or an exception is thrown if
+ * any required parameters were not present as properties. Then the denormalizer
+ * walks through the given map of property names to property values to see if a
+ * setter method exists for any of the properties. If a setter exists it is
+ * called with the property value. No automatic denormalization of the value
+ * takes place.
